Well, yes - I have seen Unity 3D and as it exist already a little longer it certainly has already a few nice examples. But what I'm interested is more - why should O3D be outdated? Is there anything in their way of technology that would prevent doing 3D graphics as seen in Unity?
Also they seem to aim at rather different targets. O3D is about creating an open webstandard. Unity3D is a proprietary 3D engine that can run as plugin on some platforms (windows+mac). O3D has to be at a low level to succeed - basically offering a way for web-programmers to access the 3D capabilities of graphic cards with tools which they know (javascript). Unity 3D is an excellent engine with a real nice price, but it doesn't look like a tool for web programmers but like a tool for desktop programmers which want to have their desktop applications also running in a browser.
